Air Velocity Transmitter for HVAC Applications
EE 65 SERIES
 |
EE65 air velocity
transmitters are ideal for accurate
ventilation control
applications.They are operating on an
innovative hot film anemometer
principle. The E+E thin film sensor
guarantees very good accuracy at low
air velocity, which is not possible for
conventional anemometers with
commercial temperature sensors or NTC bead
thermistors.
EE65 series are available with current or
voltage output, the measuring
range and the response time can be selected
with jumpers by the user.
Low angular dependence enables easy, cost-
effective installation

Air
Velocity Transmitter for measurement down to ?0? m/s
EE 66 SERIES
|
EE66 air
velocity transmitter series are designed for
high accuracy
measurement of lowest air velocities. It is
the ideal solution for laminar
flow control and special ventilation
applications. The E+E thin film sensor is
operating on an innovative hot film
anemometer principle. This guarantees
excellent
accuracy for air velocity down to almost 0
m/s, which is not possible for
conventional anemometers with commercial
temperature sensors or NTC bead
thermistors EE66 series are available with
current or voltage output,
the measuring range and the response time
can be selected with jumpers
by the user.

High-Precision Air / Gas Velocity Transmitter for
Industrial Applications
EE 75 SERIES
|
The EE75
series air velocity transmitters were
developed to obtain
accurate measuring results over a wide range
of velocities and temperatures.
A high-quality hot film sensor element based
on cutting- edge thin film
technology ensures maximum sensitivity, even
at lowest mass flows.
At the same time, the innovative probe
design produces reliable
measuring results at high flow velocities of
up to 40m/s (8000ft/min).
The integrated temperature compen- sation
minimises the temperature
cross-sensitivity of the EE75 series which,
combined with the robust
mechanical design, allows it to be used at
process temperatures
between -40 to +120°C (-40 to 248°F).

In addition to air
velocity and temperature values, the
transmitter calculates the
volumetric flow rate in m³/h or
ft³/min. The cross section of the
duct needs to be
determined for this purpose and the
volumetric flow rate can be
displayed and
directed to one of the analogue
outputs.
The EE75 series can be used to
measure the velocity of other gases
as well,
although a correction has to be
applied to the unit at the factory. |
